What is the equation of the line that is parallel to the
given line and passes through the point (-3,2)

Answers

Answer:

Step-by-step explanation:

A parallel line will have the same slope as the reference line. In this case, I don't see the "given line" as promised in the question. If it does appear, and it looks like y = 5x + 3, for example, the slope is 5 and the new line will have the same slope.

If this slope is correct, we can start the equation for the parallel line that goes through point (-3,2) by starting with:y = 5x + bWe need a value of b that forces the line to go through point (-3,2). We can do that by using the given point in the equation and solving for b:y = 5x + b2 = 5(-3) + bb = 17The parallel line to y=5x+3 isy = 5x + 17See attachment.

Max can run 10 miles in 2 hours. At this rate, how long will it take him to run 25 miles

Answers

Answer:

Step-by-step explanation: 10 miles per 2 hours is the First step. Knowing this helps a lot. Next you need to understand your solving for 25 miles. 10 goes into 25 2.5 times. This means you need to multiply the time by 2.5 as well. That would be 5 hours.

It took a cheetah 45 minutes to run from Jungle A to Jungle B.
Its average speed was 80 km/h. Find the distance between
the two jungles.

Answers

so you need to find 3/4 of 80 (60 Km/h)

and since 45 minutes is 3/4 of an hour

your answer is (60 Km/h)

Answer:

The distance between the two jungles is 60 km

Step-by-step explanation:

cheetah is going 80km/hr or (80km/60min)

using this 45min is 3/4 of 60 min

and 3/4 of 80km is 60km

So basically

[tex]\frac{80km}{1hr} = \frac{80km}{60min} * \frac{0.75}{0.75} = \frac{60km}{45min}[/tex]

Answers

Answer:

no they are different numbers, however their signs are inverted

Step-by-step explanation:

Answer:

Step-by-step explanation:

-2x+3 is not the same as 2x-3 because, let's say we set each equation equal to something...

-2x+3 = 10 2x-3 = 10

-3 -3 +3 +3

------------------ -----------------

-2x = 7 2x = 13

x = [tex]\frac{7}{2}[/tex] x = [tex]\frac{13}{2}[/tex]

x = 3.5 x = 6.5

As we can see, these equations are not the same, because, when we set them equal to the same value, the answers are different.

Answers

Answer:

5.8

miles

Step-by-step explanation:

Since area is l×b or l×l since its a square(sides are equal) we can conclude that S×S=33.64

Another way to represent this is

[tex] {s}^{2} = 33.64[/tex]

to get S we can square root both sides

[tex]s = \sqrt{33.64} [/tex]

[tex] \sqrt{33.64} = 5.8[/tex]

Therefore S=5.8miles

Answer = about 5.82 miles squared

Explanation: The shape is a square meaning all of the side lengths are the same. So the square root of 33.84 is 5.82 and 5.82 to the second power is about 33.84.

can anyone please help me with this really quick

Answers

Answer:

Step-by-step explanation:

The sum of three numbers is equal to 185, so we can start with this equation, where x is the first number, y is the second, and z is the third:

x + y + z = 185

They tell us that y is 5 times greater than x, so we can insert that equation in for y in the original equation:

x + (5x) + z = 185.

And we are told z is 13 less than y, so we can insert that equation as well by using the equation before:

x + (5x) + (5x-13) = 185

So now we can combine like terms and solve for x.

6x + 5x - 13 = 185

11x - 13 = 185

11x = 198

x = 18

But we're not done, we still need to solve for the second number, which is y. So we insert the number for x into the original equation we have for y, which is that it's 5 times greater than x:

y = 5x

y = (5*18)

y = 90

Answer:

y = 18

Step-by-step explanation:

Direct variation means y will change by the same factor x does. When x changes by a factor of 15/10 = 1.5, the value of y will change by that same factor

x = 10, y = 12

x= 15, y = 1.5×12 = 18

The new value of y is y = 18.

_____

Written as a proportion, you have ...

y/15 = 12/10

y = 15×12/10 = 18

Written as a direct variation equation, you have ...

y = kx

12 = k·10 ⇒ k = 1.2

y = 1.2·15 = 18 . . . . for x=15
